The one who lights-up the world

How many of us have time to look-up every day, admire the one who is lighting-up the world. The Sun provides energy to earth. The quantum of energy thus received on the surface of the earth in an hour’s time is equal to the total consumption of power by human kind in a year. Why are we not using this potential source. Instead, we are relying on natural fossils, other conventional sources of energy which will have an adverse impact on the nature around.

Are we short sighted, think of short term gains and not the lond term benefits?!
